Why may dark graphite areas appear shiny in a photograph?

Answer and explanation

Correct answer: The graphite layer reflects light

The governing material concept is graphite reflectance. When dark graphite is built up densely or burnished with firm pressure, its particles form a relatively smooth surface that can reflect light toward the camera. This reflected highlight makes the area look shiny in a photograph, so option A is correct. Paper does not normally emit light, pencil does not change colour by itself, and transparency is not the cause of the sheen.
